======My element is Boron which'has a signal of B. It is a metal type rock, its colour is black or brown and it is 5th on the periodic table, which means it is the 5th lightest from the atoms. boron is a type of metalloid. It is usually found in solid form and its melting point is 2076°C and its boiling point is 3927°C. Boron has 5 proton and 6 nutrons, also has 5 elecrons orbiting around the nucleus. The nucleus is made up of protons and nutrons. Amorphous boron is used to make green flares.
